NVIDIA To Build Seven AI Supercomputers For U.S. Nuclear And Energy Research

Washington D.C., United States - NVIDIA, the leading force in artificial intelligence computing, has announced a historic partnership with the U.S. Department of Energy (DOE) to dramatically accelerate American scientific and defense capabilities. NVIDIA founder and CEO Jensen Huang revealed the collaboration, stating the DOE has placed orders for AI chips valued at an unprecedented $500 billion. The core of this deal involves NVIDIA and its partners building seven new, exascale-class AI supercomputers dedicated to two critical missions: advancing national security through nuclear weapons stewardship and pioneering the future of clean energy via nuclear fusion research.

The sheer scale of this computing initiative is staggering. Two primary systems, named Equinox and Solstice, will be built for the Argonne National Laboratory in Illinois. Equinox, slated for a 2026 launch, will feature 10,000 of NVIDIA's latest Blackwell GPUs. It will be followed by the colossal Solstice system, a 200-megawatt behemoth integrating over 100,000 Blackwell GPUs to deliver a combined AI performance exceeding 2,200 exaflops. NVIDIA executive Dion Harris emphasized this collaboration aims to "significantly boost America's scientific research and development productivity and establish U.S. leadership in AI".

These supercomputers will serve a dual-purpose mission critical to U.S. interests. A significant portion of their unmatched computing power will be directed toward the National Nuclear Security Administration (NNSA) for classified work on the nation's nuclear arsenal. This includes sophisticated simulations to ensure the safety, security, and reliability of nuclear weapons without physical testing. Concurrently, the systems will perform open science research, fueling ambitious projects in foundational AI models, agentic AI, and the complex physics modeling required to make nuclear fusion—a potential source of limitless clean energy—a reality.

The announcement arrives amid intense global technological competition, particularly with China. During his remarks, Huang positioned the investment as pivotal for American leadership, stating, "We want America to win this AI race. No doubt about it". He linked the push for domestic manufacturing and AI supremacy to broader political agendas while also expressing concern over losing access to the Chinese market, noting, "China is a very important market". This deal underscores the U.S. government's strategy of leveraging cutting-edge commercial technology to maintain a strategic edge.

Beyond Argonne, the DOE partnership extends to the Los Alamos National Laboratory in New Mexico, a cornerstone of the U.S. nuclear program. Two systems named Mission and Vision, expected to be operational by 2027, will be powered by NVIDIA's next-generation Vera Rubin platform. The Mission system will be dedicated to classified NNSA applications, while Vision will support open scientific research. This builds on existing collaborations, such as the Doudna supercomputer at Lawrence Berkeley National Laboratory, creating a networked ecosystem of unparalleled AI research infrastructure across the country.

The technological foundation for these giants is NVIDIA's full-stack accelerated computing platform. This includes the groundbreaking Blackwell GPU architecture, designed for trillion-parameter AI models, and the high-performance NVIDIA Quantum-X800 InfiniBand networking that connects thousands of chips to act as a single, coherent supercomputer. This infrastructure is not just about raw power; it is engineered to fuse high-performance computing (HPC) with artificial intelligence, enabling entirely new scientific methods.

This U.S. endeavor mirrors a global surge in sovereign AI investments. NVIDIA is simultaneously powering Europe's first exascale supercomputer, JUPITER in Germany, which is tackling climate science and quantum simulation. Similar large-scale projects are underway in Japan, South Korea, and Taiwan, as nations race to build independent, state-of-the-art AI research capacity. The DOE deal represents the most direct and substantial investment in using this capability for dual-use technologies that blend groundbreaking science with national security imperatives.

The construction of these seven supercomputers marks a definitive moment in the convergence of AI, national strategy, and big science. By providing U.S. researchers with what Huang described as a "universal scientific instrument" of unprecedented scale, the project aims to catalyze discoveries from the atomic level to the cosmic scale. It solidifies AI supercomputing as the new bedrock for geopolitical competition and scientific ambition in the 21st century, with the United States making a $500 billion statement of intent to lead from the front.
